Modu got the final assembly line of the DC-11 passenger aircraft, and this time even AVIC Southwest was able to get some pretty good soup and water because of this project, just like even the MPC-75 produced by the United Passenger Aircraft Company, a subsidiary of AVIC Southwest, is still subcontracted to part of the business to AVIC Northeast's company.

After all, the aviation industry is a place that reflects the overall strength of a country, even if there are two competing aviation manufacturing companies in a country, but there is still cooperation in the competition, this phenomenon is certainly not uncommon, and even promoted to the international is still the case, between the two countries competing with each other, not the same is you have me, I have you?

Subsequently, the group visited Guiyang Aviation Industrial Zone again, including the manufacturing of aircraft landing gear units, as well as the large-scale manufacturing of general fasteners of the standardization factory, but the final end of the visit is still 0112, there is also a large project that Vice Chairman Liu has paid attention to for a lifetime.

After visiting along the way, the old man was obviously a little tired, but as soon as he heard that this time he was going to visit the last major improvement project of the lightning fighter family in the airframe, and it was also a key project related to the navy, he vaguely knew what project Yang Hui took him to see this time.

Although the carrier-based lightning is an international project that discloses the progress of the project, it still has a fairly high level of confidentiality in the AVIC Southwest 0112 Institute, and the work site of the project team is also specially opened.

Wu Binglin, who was in charge of the development of the lightning fighter all the way, and the chief engineer of the J-18 are the same brothers, and from the time he officially took over the development of the lightning at the age of 44, four years have passed since 93 years now, and the lightning fighter of that year has now begun to be delivered and formed combat effectiveness.

In the nineties when the international situation was changing, the lightning fighter designed by him still won a lot of orders with excellent cost performance, continued the important market for the export of military fighters of the republic, and retained the valuable market developed by the aviation industry after decades. A fighter that is enough to occupy a place in the international market of mid-to-high-end single-engine fighters.

The deluxe version of the lightning has a fly-by-wire + PW-1120 + DSI intake tract + in-flight refueling capability, although it is said that it is handed over to Embraer and Northrop in the external publicity, but if you think about it a little, you will know that if the fighter does not have the participation of the chief designer who accompanied it all the way, if you want to easily complete the improvement, even if it is a Yankee.

Therefore, at the beginning of the luxury version of the lightning project last year, Embraer and Northrop jointly issued an invitation letter to invite Chief Wu Binglin to Embraer to preside over the project improvement.

Being able to perfect the Lightning into a real third-generation fighter in his own hands, this kind of lure. Confusion was absolutely irresistible to the chief designer of Lightning, but in the end, Chief Wu still chose to stay in China, because he knew that he was first and foremost the military fighter designer of the Republic.

The Republic already has two chief designers of third-generation fighters in the strict sense, so the demand for this aspect is not so urgent, so Chief Wu chose the field of chief designer of carrier-based aircraft, which is still blank in the country, at least for the Republic, an excellent chief designer of carrier-based aircraft is more important at this time than the chief designer who can design third-generation fighters.

Chief Engineer Wu, who chose to stay in China to develop carrier-based aircraft technology, may not have presided over the design of the third-generation fighter on the side of Embraer, but he is still happy to do it, and every day he leads the technical team to conduct various tests on the modification of the lightning's carrier-based aircraft, since the beginning of the project in 90 years, to the present 93 years, more than three full years have passed.

.......

When the group walked in front of the core carrier-based lightning prototype, Chief Engineer Wu had already stood next to the plane early, and he had a special feeling for this fighter that he had been designing and improving.

Although the Lightning is no longer the most advanced fighter in China, the Su-27 that has just been delivered in front of the troops, and the domestic fighter in the design is also stronger than the other. However, now the lightning fighter behind Chief Wu is still a dazzling star.

"Chairman, welcome to the project department of our republic's first self-developed carrier-based fighter, and now what you see is the shipborne modification of the lightning fighter that we have been building for many years, and it has just left the final assembly line for less than half a month, from the most ....."

With the follow-up Yang Hui and several other bigwigs walking into this hangar that seems inconspicuous from the outside, the surprise, ecstasy, and praise of the improved carrier-based lightning fighter in front of him are always endless, especially Vice Chairman Liu, who came in first, trembled his hands, almost walked to the front of the plane step by step with red eyes, and after squatting down, he carefully stroked the stout landing gear of the lightning as if he was caressing his children and grandchildren.

The cold steel has magic at this time, it is also iron-carbon alloy steel, and the ship-based lightning landing gear is not only thicker than the landing gear used by the land-based type, but also has gone through many times of 10,000-ton press forging process before, and the strength of the landing gear is far from being comparable to the landing gear used by the land-based type.

Chief Wu also recalled: "It is not very difficult to design this landing gear, we have the landing gear design of the MiG-29K and F-4 Ghost as a reference, so there is no structural problem with the landing gear." The reason why the prototype is only now made is because it took us a year and a half to fabricate this landing gear, during which we used different processes to build hundreds of sets of landing gear, but because we did not master the appropriate process before this, all of them broke during the test, which cost a lot of money. It is only now that we have succeeded in manufacturing a qualified product that can withstand the huge kinetic energy of the catapult. ”

In this shipborne modification design, not only the rear landing gear needs to be strengthened to adapt to the huge impact of the aircraft landing, but also because the aircraft is a carrier-based aircraft for catapult aircraft carriers, the manufacturing requirements of the front landing gear are actually more stringent than the rear landing gear, but fortunately, it was successfully manufactured in the end, and the cost is naturally higher manufacturing costs and more complex designs, as well as heavier landing gear weight.

Vice Chairman Liu visited a US aircraft carrier 10 years ago and had close contact with carrier-based aircraft, and under the introduction of the Americans, he knew what the most important part of the nose landing gear of the carrier-based aircraft was, so he reached out and picked up a connecting rod located in front of the landing gear, which did not seem to be strong.

At first, I wasn't able to pick it up, but the feeling was familiar: "That's it, this is the connecting rod between the landing gear and the catapult, and when the plane is ejected, it is the only part that can transmit the pull generated by the missile launcher, and now we can make this thing ourselves, I'm really happy!"
